CLOCK-CASE.

SPECIFICATION forming part of Letters Patent No. 374,516, dated December 6, 1887.

Application filed June 16, 1887. Serial No. 241,473.

To all whom it may concern:

Be it known that I, ARCHIBALD BANNA- TYNE, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Clock-Cases; and I do declare the following to be a full, clear, andexact description of the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in clock-cases, the object being to provide simple, convenient, and cheap means for securing the dial and its accompanying parts to the frame-plate and the sash-ring to the dial-mat, such means to be of finished appearance, and facilitating the assemblance of the clock in the case and the care of the clock, whether for ordinary attention or repair.

With these ends in view my invention consists in the combination, with a front frameplate having a circular opening, of a circular dial-plate and a dial-mat made in one piece and set into such opening and secured to the said plate, a dial secured to the dial-plate, and a sash-ring removably secured to the mat, which projects forward from theframe-plate.

My invention further consists in the combination, with the front frame-plate, of a dial and a dial-mat permanently connected therewith, and the latter projecting forward therefrom, a sash-ring carrying the glass, and looking mechanism for removably securing the ring to the mat, such mechanism including inclines for drawing the ring up'to the plate and compensating for variations in the thicknes of the glass.

My invention further consists in the combination, with a front frame-plate, of a dial and a dial-mat permanently connected therewith and the latter projecting forward therefrom and having a slotted flange, a sash-ring carrying the glass, and inclined springs secured within the ring and passing through the slots in the flange of the mat to engage with the inner face of such flange when the ring is turned.

In the accompanying drawings, Figure 1 is a View, in front elevation, of a clock-case embodying my invention with the sash-ring removed and shown in rear elevation. Fig. 2 is a view thereof, in vertical section, on the line a b of Fig. 1, with the sash-ring in place; and

(No model.)

Fig. 3 is a detached sectional view of the sashring on the line 0 d of Fig. 1.

The frame A,which may be of any approved construction, is provided with a front frameplate, B, having a circular opening, C, located about midway between its upper and lower ends. The dial D, as herein shown, iscircular and secured to the dial-plate E, which is made in one piece with the dial-mat F, the same being flaring and provided at its outer edge with a flange, G. and the plate and mat forming a cup-shaped piece adapted to be set into the opening C, in which it is secured by solder, H, or by other means.

The sash-ring I is provided with two inclined springs, J J, located at opposite points within it, and having the twofold function of securing the glass K in the ring and of securing the ring to the mat, which is provided at opposite points with slots L L, adapted to receive the said springs when the same are brought into alignment with them, the en gagement of the inclined springs with the 1nner face of the flange G when the ring is turned operating to draw the ring toward the frameplate A until its edge engages therewith. The springs also yield sufficiently to compensate for variations in the thickness of the glass employed--an important economic feature of the present construction, as it enables cheaper grades of glass to be used. To remove the ring, it is turned until its springs are in align-' ment with the slots in the matting, and then drawn away from the frame-plate.

I would have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a clock-case, the combination, with a front frameplate having a circular opening therein, of a circular dial-plate and a dial-mat made in one piece and setting into such opening and secured to the said frame-plate, a dial attached to the dial-plate, and a sash-ring removably secured to the dial-mat which projects forward from the frame-plate, substantially as set forth.

2. In a clock-case, the combination, with a flat front frame-p1ate having an opening therein, of a dial and a dial-mat permanently attached thereto, the said dial-mat projecting forward therefrom, a sashring carrying the glass, and locking mechanism for removably' securing the glass to the mat, such mechanism including inclines for drawing the sash-ring to the plate and adapting it to be set to compensate for variations in the thickness of the glass, substantially asset forth.

3. In a clock-case, the combination, with a front frame-plate, of a dial and a dial-mat permanently connected therewith, and the latter projecting forward therefrom and having a slotted flange, a sash-ring carrying the glass,

and inclined springs secured within the ring ARCHIBALD BANNATYNE.
